NON-SEPABABLE LINK CUFF-BUTTON.

To all whom it may concern and it'consists essentially in the combination of a pair of button or head members proper,

Be it known that we, CHARLES H. ALLEN and 'CHARLEs J. CALLAHAN, citizens of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have jointly invented certain new and useful Improvements in Non-Separable Link Cuff-Buttons, of which the following is a specification.

Our invention relates to link cufi"-buttOns,

7 link or bar member will lie centrally of and .at substantially right angles to the heads, 20'

tilted or closed position the said bent portion will lie materially nearer one end of the longitudinally of the latter, but when in the head than the other, all as more fully hereinafter set forth andclaimed.

By means of our improvement, we are on abled to produce a solderless and comparatively inexpensive link cufi-button in which the head members thereof are capable of being tilted 0r swung inward toward each other 90 from the normally open position, means being provided for holding the heads against movement in'a contrary direction.

The invention further resides in arranging and mounting the pintles or pivot portions of the link with relation to the heads so that, when in normal use, the link portion.

proper will lie centrally of the heads, but the pivots themselves will be eccentric, 0r non-central to them, thereby permitting the use of materially shorter links as compared with similar heads having centrally pivoted links.

In the accompanying sheet of drawings, Figure 1 representsa front elevation of our improved link cuff-button in the normally open position; Fig. 2 is a corresponding top plan View; Fig. 3 represents the button in the fully closed position; Fig. 4 is a correponding edge or top plan view; Fig. 5 is a transverse sectional view, in enlarged scale, taken on line 5-5 of Fig. 1; Fig. 6 is a vertical central sectional View, taken-on line 66 of Fig. 5; Fig, 7 is a similar view, showing the link swung downward, the other head member being omitted; Fig. 8 is a horizontal sectional view, taken on line Specification of Letters Patent.

Fig. 14: is a plan view, enlarged, of the corre- -s ondin link' and Fi 15 re resents an b 7 b p edge view of it.

The following is a more detailed description of. our improved link cult-button and the. manner of operation The article as a whole is designated in the drawings by A, which includes the two head members a and b and the link a pivoted to and connecting them. The head members may be alike and have any desired form and ornamentation; we prefer, however, the ellipsoidal shape. Each head consists of the following parts, produced from suitable sheet-metal stock, viz. :'the outer cap or front 0 having an upturned peripheral flange; a substantially flat, resilient disk 6 having, as shown, a T-shaped recess formed therein, adapted to receive an end portion of the link member, and the outer back disk or plate (Z; and having the several members disposed or arranged substantially as shown, and secured together by inturning the caps flange to form the rounded or beaded edge 0 The link member a is formed from somewhat heavier and different sheet-metal stock than is employed in the said head members. The body part of the link is substantially flat and narrow, its two end portions being bent at substantially right angles. e prefer to have the bent portions disposed so as to face in opposite directions with respect to the plane of the body part of the link, as clearly shown, although both the bent ends may be disposed on one side, as represented in Fig. 15. At or near each terminal of the fiat portion of the link is formed a pair of oppositely disposed lateral shoulders n adapted to engage the back 0?, constituting a stop for limiting the angular movement of the head. The elongated neck or bent portion a is somewhat narrower than the said shouldered part and terminates at its free end in the laterally extending trunnion-like members if. The width of the slot or opening 6Z1 formed in disk d and the registering recessed portion 6 of spring 6 serve as a lateral support for the part n of the link when the members are assembled, the trunnions or pintles n at the same time being movably seated in the corresponding recess 6 of the spring and retained in place by the superimposed fixed disk d, all as clearly represented in the drawings.

The assembled members composing our improved link cuif-buttonA appear substantially as shown in Figs. 1, 2, and 13, when in the open or normal position wherein the link 72 extends horizontally between and connects the two head members a and b, the said connecting member being in the plane of the central or median line wa:, the latter being indicated in Figs. 1, 11, and 12. The respective pivot points 71, on which the'heads swing are located below or at a distance from and parallel with said median line. As thus devised, either head when tilted at right angles, as indicated in Fig. 12, may be readily inserted endwise through both the two registering end buttonholes of a cuff and then swung back to its open or normal position, the spring 6 meanwhile yielding sufficiently during the operation. Since either head is capable of being swung or tilted on its pivot, the insertion may be effected from the right or left, at will. If desired, both heads may be tilted or folded so as to lie flatwise and parallel, as shown in Figs. 3 and 4. By thus hinging the link to the heads at points quite a distance from the central line 50-50, the link may be made materially shorter than if it were centrally pivoted to the heads, thereby, when in use, correspondingly reducing the lateral space or opening lying between the outer ends of the cuff. a

While we have represented the body portion of the link as being comparatively narrow, thereby permitting it to be turned in the buttonholes of the cuff, we do not desire to confine ourselves to a link having the narrow body-portion, which, while it has the advantage of permitting the link to be turned in the button holes of the cuff is not essential to the perfect operation of the button.

Having thus described our invention, what weclaim and desire to secure by U. S. Letters Patent is In a link cuff button, a pair of button heads each comprising a back plate, a dished cap or front plate having an inwardly flanged edge serving as securing means for the backplate, and an oval-shaped resilient disk mounted within the cap plate in back of the back plate, said disk having a T- shaped recess and the back-plate having a slot registering with said recess and disposed at right angles to the head of the recess, both the slot and the recess being eccentric to the center of the button head, a link having T- shaped ends disposed to project in opposite directions with respect to the plane of the body of the link, said T-shaped ends of the link extending through the slots inthe back plates and lying within the recesses in the resilient disks and shoulders at the ends of the body portion of the link which engagethe back plates of the button headsand act as stops for limiting the movement of the latter, the link having a curved edge to reduce the width of the link intermediate its ends. v

In testimony whereof we have afiixed our signatures in presence of two witnesses.
